Metabolism of Leishmania: proven and predicted

Abstract

The complete analysis of the genomes of three major trypanosomatid parasites has facilitated comparison of the metabolic capabilities of each, as predicted from gene sequences. Not surprisingly, there are differences but is it possible to correlate these with the lives of the parasites themselves and make further predictions of the meaning and physiological importance of the apparently parasite-specific metabolism? In this article, we relate gene predictions with the results from experimental studies. We also speculate on the key metabolic adaptations of Leishmania and reasons why it differs from Trypanosoma brucei and Trypanosoma cruzi.
